Equation: a^2 + b^2 = c^2

18^2 + 16^2 = c^2

324 + 256 = c^2

C^2 = square root 580

Square root 580 reduces to 2 square root 145.

As a decimal that is: 24.08

Rounded to the nearest tenth: 24 inches.

Can you answer these 3 questions for me plz

A.
$1hr \: 15min = 75min$

$c = 0.22t = 0.22 \times 75 = 16.5$

cost is $16.50

B.

$26.40 = 0.22 \times t$

rearrange to solve for t:

$t = \frac{26.40}{0.22} = 120min$

C. This is the same as part B, only the rate changed

$t = \frac{26.40}{0.25} = 105.6min$

they ask for the greatest number of minutes, so we round down (take the floor of the value).

the answer is 105 minutes.
